Solution Overview

Problem

Existing vacuum cleaners face challenges in providing users with convenience during the dust discharging process, as they often scatter dust or require complex procedures, and current solutions do not effectively separate and discharge large dust and fine dust simultaneously.

Innovation Solution

A dust collector with a first and second dust storing unit, where large dust and fine dust are collected separately and compressed using a compression device, allowing for simultaneous discharge through a lower cover part that opens both units in the same direction, preventing scattering and simplifying the discharge process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If dust is discharged from a single dust container, then the discharge process is simple, but dust and fine dust scatter during discharge

Engineering Contradiction:
Improvedust discharge processVSAvoiddust scattering
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The dust container is divided into two separate storage units: a first dust storing unit for collecting dust and a second dust storing unit for collecting fine dust. Each unit has its own discharge opening, allowing controlled discharge of different dust types separately, preventing scattering while maintaining operational simplicity.

Inventive Principle:
Principle #1Segmentation

2Object-affected harmful factors

If dust and fine dust are collected separately in different units, then dust scattering is prevented, but the device complexity increases

Engineering Contradiction:
Improvedust scatteringVSAvoiddust container structure
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The second dust storing unit is disposed inside the first dust storing unit in a nested configuration. Both units share a common discharge opening at the bottom, allowing separate collection of dust and fine dust while maintaining a compact overall structure and avoiding excessive complexity.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If a compression device is added to compress dust, then dust discharge convenience is improved, but the device complexity increases

Engineering Contradiction:
Improvedust discharge convenienceVSAvoidcompression mechanism
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The compression device is configured to compress dust in both the first dust storing unit and the second dust storing unit through a single mechanism. This multi-functional design improves dust discharge convenience for both dust types while avoiding the complexity of having separate compression devices for each unit.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A dust collector disclosed herein includes a first dust storing unit to collect dust firstly-separated from air by a first cyclone, a second dust storing unit to collect fine dust secondly-separated from the air by second cyclones located above the first cyclone, a lower cover part coupled to a first dust container to form a bottom surface of the first dust storing unit and the second dust storing unit, and rotatable based on the hinge to simultaneously open the first and second dust storing units, such that the dust and the fine dust are simultaneously discharged, and a compression device rotatably connected to the lower cover part so as to rotate in a reciprocating manner to compress the dust collected in the first dust storing unit.
